I need to purchase 30-50 18650 Li-ion batteries.  There is such an enormous range of specifications for this cell that it is mind boggling. I see specs from 1000 mAh up to 6000 mAh. I find that difficult to believe. I am looking for longevity and quality more than capacity. These will be used in a transmitter sending telemetry data. The transmitter will be active for 4 minutes at a time drawing 1.0 amps. Has any Expert seen a brand comparison done that is not manufacturer sponsored rating several different brands? It would be great to see some impartial ratings. I do not want a cell that is very low for obvious reasons nor do I want to push the limit of capacity and sacrifice longevity. Any suggestions would be welcomed. I prefer to buy this type of item either from Amazon or DigiKey.

Lenovo T430s. I've noticed it is rather warm under the top left of the computer. Even though I am using it in front of a fan. It's cooled down some as the fan blows. Actually it is the top left side more than the bottom and also the top left rear. What parts are inside the top left of the laptop? Thanks

Hello, All.

On my S5000PAL Server Board, it has the

Intel® RMM NIC Connector

My question is...
What is the name/model number of the WHITE Ribbon that connects to this card and to the board?
So I can attempt to find it on eBay or another site.

All I need is the white ribbon and I will be good to go.
Any help on this would be great.


This shows the connector closer up. J2A1
Need Help understanding Mosfet IXTL2N450 .   It is a High Voltage N-Channel Mosfet with a low gate.

I am new to mosfets so please bear with me.  

I set up a basic circuit on a bread board to understand this Fet better.  

I am using 5v because it is easier to work with than my 2kv power supply I intend to use after understanding this fet better.

Problem:  When I apply 5v+ to the drain I am measuring 5v+ at the Source.  When I apply 5v+ to the gate it does nothing.... confused.  

Why is the drain 5v passing to the source without the gate voltage being applied?

Please school me. Thank you.

I have a 2016 WDS (with ADK, WinPE, MDT) server fully installed with all the required and appropriate components (newest versions) and working now.

DHCP is working (on different server with option 66 defined - WDS server name/IP) as I can see the server when I PXE boot one of our HP desktops.

I managed to upload an .iso of W10 1903 to the WDS server, create boot and install images without issue.

I then booted an HP desktop to PXE, found the WDS server, authorized the PC (I set that option) and successfully downloaded W10 1903 unto the PC without issues.
Note that I deleted al 4 partitions on that PC when it prompted me re. drives and created one single large partition. I believe W10 then automatically makes additional partitions as needed as I did not make them and they were there later.
I completed the setup and played with the o/s and it worked without issues.

After that worked I went through the process again with drives being formatted and a single partition (about 450 GB) being made, but this time I did not complete the setup, rather I entered Audit mode at first opportunity (language selection screen) through Ctrl/Shift/F3.
This also worked without problems and I managed to install Office 2013, as well as a few other smaller applications. Various Windows updates were also installed and it always rebooted back into Audit mode as expected.
After it was done I did a sysprep (with Generalize) and shut down the system.

Then I went back to the WDS server …
Hello to everyone,

the motherboard of my main PC is broken. It was an old gigabyte GA-Z87-HD3. Can some one help me to find the same model in the UE,because I live in italy,or even outside,old or new,at a decent price and with decent shipping times ? I thought to get the same model of motherboard because in that PC I have again Windows 10 installed wth all the programs,settngs,and so on and I want to transfer everything to a new PC with the tool "laplink pc mover". But to make this,I need that the old PC was still alive. Let me know. thanks.
Power 'and' display.

I thought that I would be able to use a micro-usb to usb-c cable to pair this Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here with this Microsoft Surface Go device

While the monitor does come on when it is plugged in using only the micro-usb to usb-c cable, it says "no signal" very briefly, and goes to black.

Is there any way to pair the devices so that the second screen will function?
Hello and Good Evening Everyone,

         Yes, I am needing an online purchase link for a 6-foot HDMI cable which will be compatible an HDMI Switch 3 to 1 4K Ultra HD box.  It will be needed to interface the Output port of this box with the HDMI input of my VIZIO television set.  Just in case this information is needed, here is a link to the location of the purchased HDMI Switch

          Thank you

Hello and Good Evening Everyone,

         I have an HDMI Switch 3 to 1 4K Ultra HD component which has stirred up some questions within my mind.  One of which is the IR port.  It is my understanding of the IR port that it is needed so the HDMI Switch 3 port amplifier selector remote control can transmit a signal needed to navigate between the HDMI channels, namely, HDMI 1, HDMI 2, and HDMI 3 respectively.  That said, I wonder how the receiver interfaces with the HDMI Switch box.  One of the accessories which came with the package is a black cable with one end having a connector on one end and an enclosed block on the other end.  Could this be the receiver for the remote which should interface with the HDMI Switch box?

          Any feedback which can be given in reply to this question will be greatly appreciated.

          Thank you

Hello and Good Evening Everyone,

         I am wondering if an HDMI Switch 3 to 1 4K Ultra HD requires an external power source.   The reason I ask is that the USB to power connector cable for the DC 5V port is not long enough to reach any of the charging USB ports of my power strip connected to the wall outlet.  

         Thank you

do i need to buy a new power , new fan and new graphics card if upgrading a 2017 motherboard, ssd, and cpu to 2019 mobo,ssd,cpu??

hoping to use my existing components here in the machine.

new ones i am looking at


intel i7 920 @ 2.67 GHZ

ntel Core i7-8700K Desktop Processor 6 Cores up to 4.7GHz Turbo Unlocked LGA1151 300 Series 95W

will this be meaningful upgrade for performance?
windows 62 os
will also get a newer ssd
my computer only has 6gb, 3gb usable since win 32.

since i have the motherboard below, does this mean i can have 32gb of RAM!!?? or is there something else that will prevent my from adding more RAM. not sure why i never did, maybe just budget.
should i really but that much or would getting to 9gb be dramatically different?
How can i upgrade the processing power, FOR WORK WHERE I USE MANY DESKTOP APPLICATIONS IN WINDOWS, components in this computer for better performance without spending more than $500?

I just added a new PC to my system.  I am using a Dell monitor that I had from before.
The screen quality is not all that good.  Is this a problem of the video card on the motherboard
or is it a problem of the quality of the monitor?  How do I determine which it is?

Headphones don't work when plugged into front or back audio jack. Audio is Reatek HD. Have twice uninstalled/reinstalled Realtek driver. Only way headphones work is to plug them in before you boot...and leave them. If you pull the earphones plug out and reinsert, the jack does not work again. The sound controller is something called WAVE audio.  Now when I want to use earphones, I have to plug them in and restart the computer.
I have just purchased QuickReport 6.0 Professional and can't get it to compile. to illustrate this I have created a trivial application as follows:
The missing file that appears to be missing is QuickRp.h  (NOT QuickRp.hpp)
I have contacted QBS software for support and they are experiencing the same problem and haven't come up with a solution so far after three days.,
any help would be appreciated.

I have a simple Form (Windows VCL 32bit application) with a TQuickRep control placed on the form and a TQRBand.
The header file of the project is as follows:
class TForm1 : public TForm
__published:     // IDE-managed Components
                TQuickRep *QuickRep1;
                TQRBand *QRBand1;
private:                // User declarations
public:                   // User declarations
                __fastcall TForm1(TComponent* Owner);
The first attempt to use it with Embarcadero C++ builder XE 10.1 Berlin gives an error messages when I attempt to save the project prior to compilation:
“Unable to find header file for component: QuickRpt”
Pressing cancel results in the same error message being displayed 6 times in total.
The code doesn’t compile as the header files are missing and the compiler error “Type name expected” is given (naturally)
The installation ran without any errors using the downloaded file QuickReportv6QR6DXE10_1_Berlin_W64_installer.exe
The PC is a Dell Precision laptop running 64 bit windows 7 Professional …

I have a Surface Pro 4 with a cover keyboard that has stopped working. It was working in January while we were travelling. When we returned home, I only used the Pro 4 with its docking station. I had occasion to use it off the docking station the other day, and the keyboard is not working. I looked under keyboards in device manager and there is no surface cover type listed. There are four HID keyboard devices listed. I looked at their properties and none of them seemed relevant and they were all working properly.

Booting up to the UEFI shows a Type Cover listed there; I disabled, rebooted, and enabled it with no result.

I'm running all the latest updates on Windows 10. I don't know how to check for latest on firmware.

I have also tried the 2-button shutdown and startup.

Any suggestions?

Laptop: Sony Vaio
Model: SVF152C29M
Product name: SVF1521B4E
BIOS Chip: Winbond 25Q64FVSIG
Motherboard: DA0HK9MB6D0 REV: D

The problem:
- The keyboard and the touchpad are not working at all anymore.

1) Assuming I will be able to replace the Nuvoton NPCE985LLA0DX part, can someone tell me if this component needs programming or do I just buy it new and replace the existing one?
2) If NPCE985LLA0DX requires programming, then with what programmer do I have to program it and from where do I take the code/image to program it?

My questions are about re-linking the kernel and rebuilding the kernel environment.
What does "rebuilding the kernel environment do"?
Is it required when re-linking the kernel?
How can I boot the old kernel if the new kernel fails, or has some wrong behavior?

I am afraid what will happen if the new kernel won't boot, or if there is erratic behavior with the new kernel.
How can I boot the previous kernel that was working fine?
Will the old kernel have trouble if I said "yes" to rebuild the kernel environment when creating the new kernel?

Why am I doing this?
I have SCO OpenServer 5.0.7 Host Edition with Maintenance Pack 5
Host Edition does not include Networking.
Enterprise Edition is needed for networking.

I don't know why, but I have some network components on the server.
Perhaps they were installed by Maintenance Pack 5

I currently have an Nvidia Quadro P2000 card, and I am installing (2) 50" 4K monitors, that require a 40' HDMI cable.
My video card is Displayport, and I don't want to have to have an adapter from Displayport to HDMI, so i've been looking for
Display port to HDMI 40' that does 4K and I can't find any.

Should I change my video card and go with a video card that is HDMI?   If so, what would be a good one that supports 5 or 6 monitors, full 4K resolution?

I'm thinking at this point, I might just try a 40' HDMI cable with a Display port adapter, but the HDMI cable will be in the wall, so I can't replace it if this
setup doesn't work.

Any suggestions?
